Can we add hosts to cluster after enabling proactive HA

[deepikadua]

Hi ,

In cluster configuration, I have enabled proactive HA, so can we add hosts to that cluster after enabling proactive HA.

Is this behaviour specific to vcenter or the plugin which I am using.

Yes, you should be able to add a host to the cluster even after the Proactive HA is enabled. Personally, I'm not aware of any such caveat. If it comes to it, you might have to disable/re-enable 'Proactive HA'. Are you seeing any issues while adding a new host?

Yes , I am getting error as "Host cannot be added to Cluster". So , wanted to confirm if this is my plugin issue or vcenter behaviour is like this.

Can you share the screenshot of the complete error? Is it of the same make and model as the other hosts in the cluster?

Cheers,

yes..everything is similar, still didnt able to add hosts when proactive HA is enabled.

when i disbaled proactive HA, then able to add hosts.

So , is it expected beahviour??

I believe this depends on the provider. Can you share the provider details to verify the documentation. I believe I have seen this with one of the providers documentation that if you remove/add ESXi hosts to cluster, it has to be reconfigured.

Thanks,
